Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients receive remifentanil-based anaesthesia during their elective operation. This is a one off treatment. Remifentanil is continuously infused intravenously at a rate of 0.15 - 0.3 mcg/kg/min. The infusion starts on induction of anaesthesia and finishes after the surgical procedure before emergence. Approximate duration of anaesthesia is between 45 and 120 minutes.
Intervention code [1] 256390 0
Treatment: Drugs
Comparator / control treatment
Patients receive fentanyl-based anaesthesia during their elective operation. For induction of anaesthesia, patients receive 0.5 - 1.5 mcg / kg fentanyl for induction of anaesthesia. During the procedure, repetitive doses of 0.5 - 1 mcg / kg, as clinically appropiate. Duration of anaesthesia is between 45 and 120 minutes.
Control group
Active

Summary
Brief summary
Modern anaesthesia incorporates the use of short-acting opioids such as remifentanil. Lately, there has been emerging evidence in the literature that some opioids might influence postoperative sleep quality for up to many months. We aim to compare sleep quality after exposure to 2 opioids regularly used in the clinical routine at Royal Perth Hospital.
